MTF charts can give us some indication of the performance of a lens. But don’t confuse the fantasy graphs* from Nikon or Canon or similar with Zeiss MTF charts, which are measured using production lenses at 10/20/40 lp/mm and thus inherently include the effects of diffraction and build variation

This MTF chart wide open at f/1.4 measured with an actual production lens is as good as many lenses ever get when stopped down.

A full MTF apertures series from f/1.4 through f/16 from a production lens with analysis is found in my review of the 55mm f/1.4 APO-Distagon.

* Fantasy-land computed MTF (not from an actual lens) that also does not take diffraction into account.
